To all 10 ham it may concern Be it known that we, CALVIN DAVEY and NnLsoN DAVEY, citizens of the United States, residing at South Vienna, in the county of 5 Clark and State of Ohio, have invented certain new and useful Improvements in Wheels for Road Engines, of which the following is a specification.

This invention relates to improvements in wheels for road engines, it particularly relating to wheel rims.

The object of the invention is to provide an effective'arrangement for equipping the rims of wheels for heavy road engines with continuous bands and connecting cleats whereby the wheels will run smoothly over a hard road bed without danger of cutting into the road and at the same time furnish sufficient traotive engagement with soft earth to prevent slippage of the wheels; a more specific object in this connection being to provide a construction which may be readily installed upon the rims of the wheels in an economic manner and in a way which will provide clearance for the heads of the wheel spokes.

In the accompanying drawings:

Fig. 1 is a side elevation of a wheel equipped with our improvements.

Fig. 2 is a perspective view of a portion of the Wheel.

Fig. 3 is a longitudinal section of a portion of the wheel rim.

Fig. a is a top plan view of a portion of the wheel rim. i

Referring to the drawings, 1 represents the rim, 2 the spokes and 3 the hub of a metal wheel such as is commonly used on heavy road engines; the upper ends of the spokes being inserted through apertures in the rim 1 and riveted to form heads 4 which usually project beyond the surface of the rim. In equipping such a wheel with our improvements we employ a pair of metallic bands 5 and 6 and a series of cleats 7. The

bands are shrunk upon the rim, one on each wider than the other and constitutes the inner band, the wear upon the wheel being greater upon its inner side because of the crown of the road. The cleats 7, which are also formed of metal, are secured to the rim 1 by rivets 9 or other suitable fastening de vices and these cleats 6 are as near as possible equally spaced and diagonally-arranged. The thickness of the metal of the rims and cleats is the same so that the outer surfaces of the cleats stand flush with the outer surfaces of the bands.

By our method of forming the bands and cleats separately, we are enabled to assemble the same upon the wheel rim in an economical manner and avoid the spoke heads 4;. The bands are of sufficient width to provide ample tread to support the engine upon hard road surfaces withoutthe danger of cutting into the surface of the road, a width of substantially four inches for the wider band and three inches for the narrower band 7 being found effective to support the ordinary traction engine on hard road surfaces, while in soft ground these bands will sink into the earth sufficiently to enable the cleats to provide the necessary traction to effectively prevent the wheels from slipping.

Having thus described our invention, we claim: 7

In a Wheel of the character described, the combination, of a wheel rim, of a pair of separate flat bands secured to the outer surface of said rim on opposite sides thereof with the outer edges of the bands substantially flush with the outer edges of the wheel rim, said bands being of a substantial width compared to the width of the wheel rim to permit said bands to sustain the load without cutting the road bed, and flat cleats secured to said wheel rim and extending from band to band but disconnected from said bands whereby the bands and cleats may all be installed separately on the wheel rim, said bands and cleats being all of the same thickness.

In testimony whereof, we have hereunto set our hands this 6th day of August, 1928.
